TECHNICAL DOMAIN

The present invention relates to a method for providing a laminate witha gripping capacity comprising at least one layer forming a support, forexample a non-woven layer, and at least one non-woven layer with loopssecured to the at least one lower layer forming a support. The presentinvention also relates to a device for providing a laminate of this typewith a gripping capacity as well as to a laminate of this type.

A laminate comprising at least one layer forming a support, for examplea non-woven layer, and at least one non-woven layer with loops, forexample a carded non-woven fabric consolidated by calendering, is usedin particular to form the looped part of a self-fastening hook and loopdevice, in particular for diapers and in particular to form a banddisposed in the front part of the diaper in a central position on thebelt, the band classically called the “landing zone”, so as to enablethe closure of the belt of the diaper by means of the engagement ofhooks emanating from legs disposed in parts of lateral ends of the rearpart of the diaper.

In the present invention, a gripping capacity is to be understood asmeaning the available volume in the non-woven fabric with loops intowhich the hooks can penetrate in order to provide the engagement.

PRIOR ART

The gripping zones of the non-woven fabrics are produced in particularby assembling a strip of fibers over a non-woven support of the SMStype. The fibers are independent during production and a large quantityof fibers is needed to produce the gripping volumes and mainly only thefibers on the surface opposite the support can engage with the hooks. Itis therefore necessary to have a large quantity of fibers and asignificant weight of product in order to have satisfactory engagementwith the hooks in order to meet the expectations of the user as regardsperformance. The large quantity of fibers also results in poorlegibility of the printing produced on one of the faces of the SMSsupport.

There is, furthermore, a contradiction between the weight of thefilaments used and the ability of the hooks to penetrate into thegripping zone. The greater the weight of fibers with the same volumethat is used, the more difficult it is for the hooks to penetrate.

In general, a strip forming the landing zone is in the form of alaminate and comprises a support element, for example an SMS non-wovenfabric, onto which can be printed, in particular, decorative patterns,and on the other hand a non-woven fabric with loops, for example acarded and calendered non-woven fabric that is secured to the upper partof the support element.

Preferably, the carded non-woven fabric must enable a user to seethrough the patterns printed onto the support element.

On the other hand, it is desirable for the engagement between thegripping loops formed by the textile element and the hooks to beoptimal. In order to do this it is necessary for the hooks to be able tobe introduced into or to engage easily in the gripping loops.Furthermore, good resistance to shearing of the loops when they aresought by a hook is preferable, as is good resistance to opening bypeeling away. It is also desirable for the user to have a good fasteningsensation upon opening that gives him or her confidence in the closurewithout any jolts and with a moderate effort. This appreciation isgenerally measured by calculating the peeling away energy. It is alsodesirable to obtain a good sensory quality associated with a sensationof softness that requires a soft touch and a textile appearance, as wellas optimization of the weight of the landing zone, and so reduced costof the product.

As a result there are requirements that contradict the desire for theprinted patterns to be able to be seen well through the loop elementwhich mean that the current landing zones, in particular those formed bytwo non-woven fabrics—respectively an SMS and a carded fabric—either donot exhibit good resistance to peeling away, whether this be the case inreality or is felt to be so by the user, or do not allow the user to seethe printed patterns on the support layer well.

WO2008/130807 discloses a laminate comprising at least one supportingnon-woven fabric and a carded non-woven fabric with loops that issecured to the support element. This laminate is produced bycalendering, thus creating multiple connection zones. There is nogripping capacity.

OBJECT AND SUMMARY OF THE INVENTION

The object of the present invention is to overcome the disadvantages ofthe prior art by proposing a method for providing a laminate with agripping capacity of the type defined above, intended in particular forforming a landing zone without thereby reducing the visibility ofpatterns printed on the support layer.

According to the invention, a method for providing a laminate with agripping capacity, intended in particular for forming a landing zone,comprising at least one textile support element, in particular at leastone non-woven fabric, for example SMS, and at least one non-woven fabricwith loops, in particular a carded non-woven fabric, secured to theupper face of the support element, which comprises the steps wherein:

a strip of non-woven fabric with loops and a strip forming a supportelement are unrolled in order to pass them into a gap formed between anupper and a lower roller in order to secure the two elements to oneanother, the face of the upper roller in contact with the non-wovenfabric with loops having, at the gap, a first speed orientated in thedirection of unrolling the laminate, or in the direction of the machineor MD, the face of the lower roller in contact with the support elementhaving, at the gap, a second speed likewise orientated in the directionof unrolling the laminate, or in the direction of the machine or MD, andcharacterized in that:the first and the second speed are adjusted so that the first speed isgreater than the second speed.

One thus obtains very simply a laminate which, while enabling excellentvisibility of any patterns printed onto the support element, exhibitsmore hook and loop fastening volume and also a greater engagementability for hooks.

According to a preferred embodiment of the invention, the first and thesecond speed are adjusted so that the ratio of the first speed to thesecond speed (or supercharging coefficient) is greater than 1.1, inparticular greater than 1.2, and in particular between 1.2 and 1.6,preferably between 1.3 and 1.5.

Preferably, at least one of the two rollers is heated and the two stripsare secured by calendering.

The present invention also relates to a laminate (1) comprising at leastone support element (2), for example a non-woven fabric, in particularan SMS, and at least one non-woven fabric (3) with loops, in particulara carded non-woven fabric, secured to the support element (1), inparticular by calendering with the first non-woven fabric, characterizedin that the curve representing the force required to stretch thelaminate along a given axis, for example the MD axis or the CD axis ofthe laminate, as a function of elongation, comprises a segment in which,starting from a zero elongation value, the force increases from zero upto a maximum force, corresponding in particular to the rupture of thelaminate, and the curve comprises an inflection point (Pi) on saidsegment.

According to another embodiment, the support element is formed by aplastic film, in particular made of a thermoplastic material.

Preferably, the support element is not elastic. In a case where thesupport element is elastic, the curve representing the force as afunction of deformation (elongation) that is appropriate to consider isthe curve of the first deformation that starts from zero deformation.

PREFERRED EMBODIMENTS

FIG. 1 shows a laminate 1 according to the invention, comprising asupport element 2 formed by a layer of SMS non-woven fabric (i.e. madeup of three superimposed non-woven layers—Spunbond-Meltblown-Spunbond)and an element 3 with loops formed by a carded non-woven fabricconsolidated by calendering.

Patterns have been printed on the upper face of the support element 2,then the two elements 2 and 3 have been sent together through tworollers 4 and 5 in order to be mutually secured by calendering, as shownin FIG. 3. According to one version, one can print onto the lower faceof the support element 2.

In the gap formed between the upper 4 and the lower 4 rollers, the twoelements 2 and 3 are pressed one against the other by the respectiveexternal surfaces on either side of the two rollers. One or both of therollers is/are heated and one of the two rollers comprises an engravingpattern.

The laminate 1 of FIG. 1 is that obtained at the output of the deviceshown in FIG. 3.

Furthermore, the respective speeds of the two lower and upper rollers atthe point of contact with the laminate passing into the gap areorientated so as to be mutually parallel in the direction of unrollingthe two elements, in particular in the machine direction or MD. However,the speed value V1 of the upper roller at the contact point with thetextile element with loops in the gap is greater than that of the speedV2 of the lower roller, i.e. of the roller in contact with the supportelement. In order to obtain the laminate of FIG. 1, the V1/V2 ratio inFIG. 3 has been adjusted so that it is equal to 1.4.

As can be seen in FIG. 3, the element with loops comprises, insuccession, connection zones, in particular formed by calendering, andzones forming the loops. The zones forming the loops are asymmetrical inform. In particular, their respective top or the middle S of their toppart (in the case of a flattened top as in FIG. 3) is offset, inparticular in the MD direction, with respect to the central point P0equidistant from the two successive connection zones between which therespective zone forming loops extends. In other words, the right-handsegment SP0 is not perpendicular to the plane of the supportingnon-woven fabric.

FIG. 2 shows the curve representing the elongation force of the laminate1 in the MD direction as a function of elongation. In order to producethis curve, the elongation at rupture test is used in the MD direction,which test consists of placing a sample with a length greater than 100mm and a width of 50 mm of the laminate 1 obtained at the output of thedevice shown in FIG. 3 between two jaws (distance between the jaws equalto 100 mm) of a dynamometer (traction speed 50 mm/min).

As can be seen, the curve increases from 0% elongation to a point R ataround 60% that corresponds to the maximum elongation force or else tothe force at rupture. Beyond point R, the curve decreases, in particularwith a steep gradient, very much greater in absolute value than thegradient of the segment between O and R.

In order to measure the inflection point one can use any classicalmethod, for example graphically by the tangent method (d2) or bypolynomial modelisation, in particular of row 4, of the curve.

On the segment between O and R, the curve comprises an inflection pointPi, at around 20%. The inflection point Pi is preferably greater than4%, in particular between 7% and 30%, more preferably between 7 and 20%.

As a function of the overfeeding, the gripping capacity will increase,thus enhancing the performance, in particular as regards shearing andpeeling away, of the laminate, in particular of the landing zone, asshown by FIG. 4.

As can be seen in FIG. 2A, if no overspeed is provided to any of therollers (V1/V2=1), the curve does not comprise the inflection point. Theresulting laminate does not have any gripping capacity.

Peeling Away Method

In order to measure the peeling away performance as a function ofoverfeeding, measurement of the resistance at the opening at 180° of anassembled hook/landing zone pairing is used. A strip of hooks that is 13mm wide and 25.4 mm long assembled over an 80 g/m² paper support with awidth of 25.4 mm is pressed onto a sample of the landing zone withdimensions of 50 mm×50 mm with the aid of a single 2 kg roller, therelative orientations of the products being identical to those used onthe diaper. Traction of 1 kg is then applied for 10 seconds to the hooksupport so as to simulate the sealing of a diaper, in particular of adiaper that has elastic flaps. The paper supporting the hook is theninserted into the upper mobile jaw of a traction frame of the Synergie200H type made by MTS System equipped with a 100 N dynamometric cell andthe landing zone is inserted into the lower jaw. The distance betweenthe two jaws is 50 mm. In order to measure the opening force, the upperpart of the frame then executes translation from the bottom to the topat a speed of 305 mm/min. One then takes the value of the maximum forcesupplied by the machine as well as any energy value corresponding to thearea below the surface of the test curve taken over the first 13 mm ofthe travel of the traction frame.

Shearing Method

In order to measure the shearing performance as a function of theoverfeeding, a 50 mm×50 mm sample of landing zone is taken that isadhered over a rigid, for example, metallic plate with double-sidedadhesive.

A strip of hooks that is 13 mm wide and 25.4 mm long and is assembledover a 250 g/m² paper support is engaged by the operator on the landingzone respecting the relative orientations of the products on the layer,and pressure is applied by the operator with his or her thumb for 3secs.

1 kg traction is then applied for 5 seconds to the hook support so as tosimulate the sealing of a diaper, in particular of a diaper that haselastic flaps.

The metallic plate supporting the landing zone is inserted into themobile upper jaw of a traction frame of the DY 30 type made by MTSSystem equipped with a 100 N dynamometric cell.

The paper supporting the hook is then inserted into the fixed lower jaw.

The movement of the frame will be in the same direction as the 1 kgtraction. The distance between the two jaws is 76 mm. In order tomeasure the opening force, the top part of the frame then executestranslation from the bottom to the top at a constant speed of 305mm/min. The test is carried out until the loop and the hook are totallydisengaged. The maximum force value on the curve that is obtained isthen taken.

In the present invention, non-woven fabric means a product obtained atthe end of the formation of a strip of fibers and/or filaments whichhave been consolidated. The consolidation can be mechanical, chemical orthermal and is manifested by the presence of connections between thefibers and/or the filaments. This consolidation can be direct, i.e. madedirectly between the fibers and/or filaments by welding, or it can beindirect, i.e. by means of an intermediate layer between the fibersand/or the filaments, for example a layer of adhesive or a layer ofbinder. The term non-woven relates to a structure in the form of a lapor strip of fibers or filaments which are interlaced in a non-uniform,irregular or random manner. A non-woven fabric can have a single layerstructure or a multiple layer structure. A non-woven fabric can also bejoined to another material such as a film in order to form a laminate. Anon-woven fabric can be made from different synthetic and/or naturalmaterials. The natural materials are, for example, cellulose fibers suchas cotton, jute, paper pulp, linen and the like, and can also includereprocessed cellulose fibers such as rayon or viscose. The naturalfibers for a non-woven fabric can be prepared by using various processessuch as carding. Synthetic materials include, but are not restricted to,for example, synthetic thermoplastic polymers which are known to formfibers that include, but are not restricted to, polyolefins, for examplepolyethyelene, polypropylene, polybutylene and the like; polyamide, forexample polyamide 6, polyamide 6.6, polyamide 10, polyamide 12 and thelike; polyesters, for example polyethylene teraphthalates, polybutyleneterephthalates, polylactic acids and the like, polycarbonates,polystyrenes, thermoplastic elastomers, polymer vinyls, polyurethanesand mixtures and copolymers of the latter.

In general, the fibers and the filaments differ mainly by their lengthand by their production method.

Filaments mean the unitary elements, with very great lengths withrespect to the diameter to which their section is assigned, extrudedcontinuously in order to directly form a strip of non-woven fabric thatcan then be consolidated by thermo-linking or any other means so as tomake it possible to achieve the desired performance and/or theirtransportation. Preferably the filaments exhibit a length greater than120 mm.

Fiber is understood to be the generic term designating a textilematerial or a textile material element with reduced length less than thelength of the filaments and able to be spun and/or used in theproduction of non-woven fabrics. A distinction can be made between twotypes of fiber—short fibers formed discontinuously with a small lengthof less than 70 mm (preferably 25 mm to 60 mm) and long fibers formeddiscontinuously with a large length of greater than 70 mm (preferably 80mm to 120 mm).

Unlike filaments that are consolidated directly after having beenextruded, fibers are collectively aligned and organized in a stripduring a carding step that is well known to the person skilled in theart. This strip can then be consolidated by thermal linking or by anyother means so as to make it possible to achieve the desired performanceand/or their transportation. According to the invention one canadvantageously use a non-woven fabric with loops that comprises highelongation fibers.

High elongation fibers are understood to mean fibers which exhibitmaximum elongation before rupture of more than 250%, i.e. fibers whichcan stretch by at least 2.5 times their length at rest and beforestretching.

More specifically, high elongation fibers exhibit maximum elongationbefore rupture of more than 300% elongation, or else exhibit maximumelongation before rupture of between 300% and 600% elongation, morespecifically between 450% and 500% elongation.

According to one embodiment, the non-woven fabric with loops compriseshigh elongation fibers, in particular at least 50% high elongationfibers.

According to the present invention loop means a filament and/or a fiberthat comprises two ends, each one joined to the support at a respectivepoint of the support or at a same point of the support. A loop can alsobe formed from a number of filaments or fibers that are joined to oneanother and of which at least two are joined to the support at one pointor at two respective distinct points. The loops can exhibit a specificdissymmetrical form here.

Non-woven fabric with loops means a non-woven fabric forming loops thatis available to a hook after being joined to the support.

In one version, one could envisage activating the non-woven fabric withloops before securing it to the support element.

Preferably, at least one support element is a non-woven fabric, inparticular an SM (Spunbound-Meltblown), an SMS(Spunbond-Meltblown-Spunbond), or an SMMS(Spunbond-Meltblown-Meltblown-Spunbond), SSMMS(Spunbond-Spunbond-Meltblown-Meltblown-Spunbond) and the like.

According to the invention, elastic is understood as meaning an elementthat, according to the test described below, has a persistence or SET′of less than 15%, preferably less than 10%, more preferably less than 5%for a stretch of 100% of its initial dimension. According to theinvention, non-elastic is understood as meaning an element that does notcome under the above definition of an elastic element. Likewise, anelement that breaks before reaching elongation of 100% of its initialdimension must be considered to be non-elastic.

One can also, for example, measure the elasticity of a laminate bydetermining its persistence by the following test:

The sample is conditioned in a normal atmosphere as defined in standardASTDM 5170 at a temperature of 23° C.±2° C. and relative humidity of50%±

5%.

As equipment, a dynamometer according to standard EN 10002, inparticular the Synergie 200, a column available from the company MTSSystems Corp, U.S.A., along with TESTWORKS 4.12. operating software isused.

The sample is prepared by cutting the elastic product (for example thelaminate of the invention) with a cutter or scissors into a sample thatis 50 mm wide in the MD direction (direction of the machineperpendicular to the plane of FIGS. 1) and 120 mm long in the CDdirection (the transverse direction, or horizontal direction in FIG. 1).

The parameters are selected as follows:

Distance between jaws: 100 mmMachine speed: 508 mm/mnNumber of cycles: 1Elongation of the product: 100% at constant speed

The product is stretched 100% by vertical displacement of the upper jaw,the lower jaw being fixed, then it is kept in this position for 30seconds, then it is returned to the initial position at constant speedwhere it is left for 60 seconds (end of the cycle), then it is stretchedagain until the product ruptures.

One then obtains the curve representing the stretching force as afunction of elongation in %, and this exhibits a hysteresis that allowsone to determine the “Set” by means of the following calculationformula:

SET=L1−L0

With:

-   L0: Intersection point with the axis of the Xs (elongation in %)    upon starting the test, i.e. at the start of the cycle.-   L1: Intersection point with the axis of the Xs (elongation in %)    upon starting the second elongation after the return to a zero force    and waiting for 60 seconds.
